@zboblamont I also have a quite complex and too expensive system (heatpump, solar panels, RF devices) for my (floor) heating, and indeed you did the right thing : insulation is the key. Your (and every user's) goal is to spend less, Honeywell's goal is to sell you their stuff (sales) and lead you into believing that it was the right choice (marketing). So if you want to get additional benefits, you can also ... double check your air tighness and ventilation, and monitor your electricity bill. Not sure if PV is an interesting alternative where you live.
One of the reason of the lack of feedback is that your OP is not really a (simple) question. Not sure what you ask opinion on, and you already did your homework. A second reason is ... summer.
